1. Fire fighting turret, comprising:
- (a) a nozzle apparatus, including a main body adapted to receive fluid under pressure, an intermediate body mounted on the main body for swinging motion about a vertical axis, and a nozzle mounted on the intermediate body for movement about a horizontal axis,(b) a control rod extending through the main body and the intermediate body, mounted therein for vertical sliding movement, and connected at its upper end to the nozzle for bringing about the said movement about a horizontal axis,(c) an elevation cylinder mounted in fixed relationship to the main body, and(d) an actuating element with an inclined slot, a vertical slot, and a guide element riding in the slots, the elements joining a movable element of the cylinder and the control rod to bring about vertical movement of the rod when the cylinder is energized.

6. Fire fighting turret, comprising:
-
(a) a nozzle apparatus, including a main body adapted to be mounted in a fixed position, an intermediate body mounted on the main body for swinging movement relative thereto, and a nozzle mounted on the intermediate for adjustment to a selected angle to the angle of the said swinging movement, (b) a source of pressure air, (c) an elevation pneumatic cylinder connected to the source to bring about the said adjustment, (d) a rotation pneumatic cylinder connected to the source to bring about the said swinging movement, (e) a pair of selector fingers pivotally mounted on a common pivot, each finger having a limit switch, and (f) a bracket movable in synchronization with the rotation cylinder to come into operative relationship alternately with the limit switchs on the selector fingers to cause oscillation of the intermediate body and the nozzle, the arc and direction of oscillation being selectable by corresponding adjustment of the fingers. - View Dependent Claims (7)
